One of these days I'll get enough time to look into this, but I was
amongst the people shouting that his device must be broken until
yesterday I ran into the same problem.

The Linux kernel is slow enough in responding to media changes that I
can swap my DVD-RAM disks around and get an "old" contents when it is
